Statistical Variation in Measures• Random variation in all measures• Greater variability if:– Rare event– Smaller hospital– Small sample size• Can lead to difficulty in making determinationthat a true improvement took place6

Approach to Statistical Variation• Step 1: consider target for an indicator• Step 2: calculate l % improvement anticipatedi t • Step 3: examine (using simple guidelines in next slides, orformal statistical tests) whether this level of improvementcould be detected statistically• Step 4: if it cannot, consider the following options:– Consider a more ambitious target– Consider making this a multi‐year target instead; do not tie exec compto indicator this year– Consider other indicators for the same problem, with more frequentobservations or greater ability to make large change– Base the baseline on longer time period (e.g. past 2 yrs)– Collect more data (e.g. more surveys)7
